CLIENT: Yancoal
PROJECT: Dredging – Cameby Downs

SCOPE OF WORK:

Within a very short timeframe prior to the wet season, remove as much material as possible from the decant water dam and deposit approximately 700 meters away into the tailings dam.

CHALLENGES FACED:

Maxitool Australia was given very little notice for this time critical project, however were able to mobilise equipment and crew on-site within one week of receiving the purchase order.

The decant water dam contained an accumulation of coal fines from the tailings dam as well as site run-off silts which were getting picked up by the in-situ electric water return pump, causing constant pump outages and damage.

ACHIEVEMENTS/OUTCOMES

Maxitool Australia conducted dredging operations using a horizontal auger dredge, removing more than 1000m3 of solids per day. Maxitool Australia also operated the site provided floccing station, allowing the slurry to shed water quicker at the discharge location. As a result, the Client was able to reinstate the clean water supply to the CHPP and eliminate unnecessary future wear on their pump.
